That's for the equation I got from the picture
4/15 of the balloons are purple. You have two darts. There are 105 combinations of hitting two balloons out of the 15. There are 6 combinations of purple balloons to be hit. This (Purple combinations over total combinations) is your probability. 6/105 simplified to 2/35 or 2:35
So your chance of picking the purple balloons, both purple, out is 2 in 35 or 2/35

Perimeter is adding all the sides.
since it is square it is 14 +14 +14 +14 = 56 miles
A-length
b-width
perimeter of rectangular floor: 2a+2b=204
<span>The length is two times the width: a=2b
</span>2a + 2b = 204
2*2b + 2b = 204
6b = 204|:6
b = 34
a=2b=2*34=68
a=68->length
b=34->width
The 10 followed by the little superscript number just represents how many decimal places you move to get your final number. So:
3.25 × 10⁴ just means you move the decimal point (between 3 and 2) four times to the right: 32500 (the decimal point would be after the last 0, so technically it's 32500.0, but you don't need to write that).
When the little superscript number is negative, you move the decimal point to the left:
6.04 × 10⁻³ = 0.00604 (make sure to add a zero before the decimal too).
When you write a standard form number, you have to make sure the number is larger than 0 and less than 10, so converting a number like 2,400,000 would be 2.4 × 10⁵, because you're moving the decimal place 5 times to get 2,400,000.
0.00147 is 1.47 × 10⁻³ because once again, you have to move 3 decimal places to the left.
